Finally worked out what was going wrong.  You need to set both the 
USB_DEBUG option on in your kernel and set the sysctl hw.usb.debug to 6.

Anyway I now have some pretty good output and have traced the code and 
am pretty certain of what is happening now.  How to fix it....I have no 
idea!  Here is the dmesg out from the time I plugge my scanner into my 
laptop:

usbd_alloc_xfer() = 0xc1951a00
usbd_transfer: xfer=0xc1951a00, flags=6, pipe=0xc239c900, running=0
usbd_dump_queue: pipe=0xc239c900

usb_insert_transfer: pipe=0xc239c900 running=0 timeout=5000
usb_add_task: task=0xc1951a84

usb_transfer_complete: pipe=0xc239c900 xfer=0xc1951a00 status=15 actlen=0
usb_freemem: frag=0xc19d9e80
usb_transfer_complete: repeat=0 new head=0
usbd_start_next: pipe=0xc239c900, xfer=0
usbd_free_xfer: 0xc1951a00
usbd_alloc_xfer() = 0xc1951a00
usbd_transfer: xfer=0xc1951a00, flags=6, pipe=0xc239c900, running=0
usbd_dump_queue: pipe=0xc239c900
usb_allocmem: use frag=0xc19d9e80 size=2
usb_insert_transfer: pipe=0xc239c900 running=0 timeout=5000
usb_add_task: task=0xc1951a84

usb_transfer_complete: repeat=0 new head=0
usbd_start_next: pipe=0xc239c900, xfer=0
usbd_free_xfer: 0xc1951a00
uscanner1: Hewlett Packard ScanJet 3400cse, rev 1.00/0.00, addr 2
usbd_set_config_no: 1
usbd_get_config_desc: confidx=0
usbd_get_desc: type=2, index=0, len=9
usbd_alloc_xfer() = 0xc1951a00
usbd_transfer: xfer=0xc1951a00, flags=2, pipe=0xc239c900, running=0
usbd_dump_queue: pipe=0xc239c900
usb_allocmem: use frag=0xc19d9e80 size=9
usb_insert_transfer: pipe=0xc239c900 running=0 timeout=5000

At this point is hangs for I am guessing exactly 5000ms.

usb_transfer_complete: pipe=0xc239c900 xfer=0xc1951a00 status=17 actlen=0

status 17 above is USBD_STALLED.  So I am guessing that the scanner is 
not responding at this point...although it seemed to respond above..no?

Can anyone point me at least in the right direction to fixing this.  Is 
it a hardware or a software problem?  If it is fixable and I can somehow 
manage to fix it, I will post my patch here.

Thanks
Chris

PS: Just added the rest of the usb dmesg output below for good measure.
